Web#define LED1 13 #define LED2 12 // funzioni timer per il led 1 unsigned long previousMillis_led1; unsigned long interval_led1; void timerInit_led1(unsigned long milliseconds) Webto keep track of the timing for turning on each LED and fading it out. The previousMillis variable stores the previous value of millis(), and the currentMillis variable holds the current value of millis(). We use a similar approach as in the previous code, but instead of using delay() to control the timing, we check the time elapsed using millis()

WebJun 11, 2015 · TL;DR Short version:. An unsigned long is 0 to 4,294,967,295 (2^32 - 1).. So lets say previousMillis is 4,294,967,290 (5 ms before rollover), and currentMillis is 10 … WebBlink without Delay is the example where the delay () function is replaced by millis () : unsigned long previousMillis=0; // millis() returns an unsigned long. Above is the shortest, easiest “Blink without Delay” sketch. The advantage is that if you want to add two LEDs in the above sketch, then add in this way : dinner and slow dancing in san francisco
